Hi this is python 3.7 . I am still learning so please explain how thanks

3.3.9. Write a function horizontalCircles (tortoise) that draws ten non-overlapping circles, each with radius 50, that run horizontally across the graphics window. Use a for loop. 3.3.10. Write a function diagonalCircles (tortoise) that draws ten non-overlapping circles, each with radius 50, that run diagonally from the top left to the bottom right, of the graphics window. Use a for loop. 3.3.11. Write a function dravRow(tortoise) that draws one row of an 8 8 red/black checkerboard. Use a for loop and the dravSquare function you wrote in Exercise 3.3.5 3.3.12. Write a function drawRow(tortoise, color1, color2) that draws one row of an 8 x 8 checkerboard in which the colors of the squares alternate between colori and color2. The parameters color1 and color2 are both strings representing colors. For example, calling dravRou (george, 'red', 'black') should draw a row that alternates between red and black
